Barriers to Dose Optimization

Theme	Resistance to Change	Limited Time & Resources	Complex Organizational Structures	Lack of Leadership Support	Variations in CT Equipment	Variability in CT Protocols
% (N=26) Respondents Reported	88% (23)	61% (16)	50% (13)	50% (13)	57% (15)	50% (13)
Thematic Description	Preference for image/appearance of higher-dose exams Concern about maintaining diagnostic accuracy	Other pressing Needs compete for time and resources	Size, decision making (centralized or localized), group relationships within organization impact ability to institute change	Other priorities (e.g., patient safety) compete for leadership time and attention	Challenge to optimize CT dose across differing machines, manufacturers, models	Large number And variability in types of protocols and use of individualized protocols
